FIELD OF THE INVENTION

The present invention relates to a display technology field, and moreparticularly to a liquid crystal display panel of column inversiondriving mode and a driving method thereof.

BACKGROUND OF THE INVENTION

The LCD (Liquid Crystal Display) possesses many advantages of beingultra thin, power saved and radiation free. It has been widely utilizedin, such as LCD TVs, mobile phones, Personal Digital Assistant (PDA),digital cameras, laptop screens or notebook screens, and dominates theflat panel display field.

Most of the liquid crystal displays on the present market are backlighttype liquid crystal displays, which comprise a liquid crystal displaypanel and a backlight module. The working principle of the liquidcrystal display panel is that the Liquid Crystal is injected between theThin Film Transistor Array Substrate (TFT array substrate) and the ColorFilter (CF). The light of backlight module is refracted to generateimages by applying driving voltages to the two substrates forcontrolling the rotations of the liquid crystal molecules.

The liquid crystal display panel comprises a plurality of pixelsarranged in array. Each pixel is electrically coupled to one thin filmtransistor (TFT), and a gate (Gate) of the TFT is coupled to ahorizontal scan line, and a drain is coupled to a vertical data line,and a source is coupled to a pixel electrode. The enough voltage isapplied to the level scan line, and all the TFTs electrically coupled tothe scan line are activated. Thus, the signal voltage on the data linecan be written into the pixel to control the transmittances of liquidcrystals to achieve the display effect.

The liquid crystal molecules have a certain property, which is that theliquid crystal molecules will be polarized if the voltage of the samedirection is applied to the liquid crystal molecules with a long periodof time. Even the voltage disappears, the property of the liquid crystalmolecules will be destroyed and can no longer be rotated due to thevariation of the electrical field. Therefore, the liquid crystal displaypanel must be driven alternately. As showing images, the liquid crystalmolecules are rotated with a certain frequency to prevent that theliquid crystal molecules fixedly lean to the same direction and lose theactivity. At present, the liquid crystal display panel supports themultiple inversion modes, such as dot inversion mode, row inversionmode, column inversion mode, and etc. The way of achieving the inversionis mainly to constantly alter the positive, negative polarities of thesource voltage of the TFT (i.e. the positive, negative polarities of thesignal voltage), or constantly alter the positive, negative polaritiesof the common electrode to realize the objective of the alternate drive.When the liquid crystal display panel normally functions, the voltagedifference between the positive, negative source voltages of the TFT(i.e. the signal voltage) and the gate voltage are different, and thus,in the same period of time, the charge effects of the TFT sources to thepixels shows to be different. Accordingly, the brightnesses ofrespective pixels in the display image differ. Ultimately, the imagedisplay effect is nonuniform.

FIG. 1 is a circuit diagram of a liquid crystal display panel of columninversion driving mode according to prior art, and FIG. 2 is a sequencediagram of the circuit shown in FIG. 1. Please refer to FIG. 1. Theliquid crystal display panel of column inversion driving mode accordingto prior art comprises a plurality of data lines, which are mutuallyparallel, sequentially aligned and vertical, a plurality of scan lines,which are mutually parallel, sequentially aligned and horizontal and aplurality of pixels arranged in array, and each pixel comprises a pixeldriving circuit inside; all the plurality of pixel driving circuits inthe pixels of the same row are electrically coupled to the scan linecorresponding to the pixel of the row; all the plurality of pixeldriving circuits in the pixels of the same column are electricallycoupled to the data line corresponding to the pixel of the column. Thepixel driving circuit comprises: a driving thin film transistor T1, anda gate of the driving thin film transistor T1 is electrically coupled tothe scan line corresponding the row where the pixel is, and a source iselectrically coupled to the data line corresponding the column where thepixel is, and a drain is electrically coupled to one end of a storagecapacitor CST1 and one end of a liquid crystal capacitor CLC1; thestorage capacitor CST1, the other end of the storage capacitor CST1 iselectrically coupled to a common electrode VCOM; the liquid crystalcapacitor CLC1, and the other end of the liquid crystal capacitor CLC1is electrically coupled to the common electrode VCOM. Because the liquidcrystal display panel shown in FIG. 1 utilizes column inversion drivingmode, referring to FIG. 3, FIG. 4, the polarities of source voltages ofthe driving thin film transistors T1 in the pixels of every two adjacentcolumns are opposite, and the polarities of source voltages of thedriving thin film transistors T1 in the same pixel for every twoadjacent frames are opposite. Specifically, with combination of FIG,FIG. 2, the driving procedure of the liquid crystal display panel ofcolumn inversion driving mode according to prior art showing a frame:the plurality of scan lines sequentially scan row by row, and N, M areset to be positive integers. As scan is performed to the Nth scan line,the Nth scan line provides a scan signal GATE(N) to the gates of thedriving thin film transistors T1 of the pixels of Nth row, and all thedriving thin film transistor T1 of the pixels of Nth row are activated.For the pixels of adjacent Mth column and M+1th column, the Mth dataline S(M) writes positive voltage into the source of the driving thinfilm transistor T1 of Nth row, Mth column, and the length of the writingperiod is t; the M+1th data line adjacent to the Mth data line S(M)writes negative voltage into the source of the driving thin filmtransistor T1 of Nth row, M+1 th column, and the length of the writingperiod is also t; because the polarity of the source voltage of thedriving thin film transistor T1 of Nth row, Mth column is positive, andthe polarity of the source voltage of the driving thin film transistorT1 of Nth row, M+1th column is negative, and the gate voltages of thedriving thin film transistors T1 of Nth row, Mth column and the Nth row,M+1th column are the same, the voltage difference formed by the sourcevoltages of the driving thin film transistors of the pixels of Mthcolumn, M+1th column and the gate voltage are different. Under thecircumstance that the pixel charge periods of the pixels of Mth column,M+1th column are the same (both are t1), the charge effects of thepixels of the two columns are different. The display brightnesses of thepixels of Mth column and M+1th column differ. Ultimately, the imagedisplay effect is nonuniform.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

For better explaining the technical solution and the effect of thepresent invention, the present invention will be further described indetail with the accompanying drawings and the specific embodiments.

Please refer from FIG. 5 to FIG. 7. The present invention first providesa liquid crystal display panel of column inversion driving mode,comprising a plurality of data lines, which are mutually parallel,sequentially aligned and vertical, a plurality of scan lines, which aremutually parallel, sequentially aligned and horizontal and a pluralityof pixels arranged in array, and each pixel comprises a pixel drivingcircuit inside; all the plurality of pixel driving circuits in thepixels of the same row are electrically coupled to the scan linecorresponding to the pixel of the row; all the plurality of pixeldriving circuits in the pixels of odd column and in the pixels of evencolumn respectively at the left, right sides of each data line areelectrically coupled to the data line.

The pixel driving circuit comprises: a driving thin film transistor T1,a charge control thin film transistor, a storage capacitor CST1 and aliquid crystal capacitor CLC1.

A gate of the driving thin film transistor T1 is electrically coupled tothe scan line corresponded with the row where the pixel is, and a sourceis electrically coupled to a drain of the charge control thin filmtransistor, and a drain is electrically coupled to one end of thestorage capacitor CST1 and one end of the liquid crystal capacitor CLC1;a gate of the charge control thin film transistor is electricallycoupled to a clock signal CK, and a source is electrically coupled tothe data line corresponded with the column where the pixel is; both theother end of the storage capacitor CST1 and the other end of the liquidcrystal capacitor CLC1 are electrically coupled to a common electrodeVCOM.

One of the charge control thin film transistor T2 in the pixel of evencolumn and the charge control thin film transistor T2′ in the pixel ofodd column is controlled by a high voltage level to be on, and the otheris controlled by a low voltage level to be on. Furthermore, the chargecontrol thin film transistor T2′ in the pixel of odd column is a P-typethin film transistor, and the charge control thin film transistor T2 inthe pixel of even column is a N-type thin film transistor; or the chargecontrol thin film transistor T2′ in the pixel of odd column is a N-typethin film transistor, and the charge control thin film transistor T2 inthe pixel of even column is a P-type thin film transistor.

The clock signal CK alternately provides the high, low voltage levels tocontrol the charge control thin film transistor T2 in the pixel of evencolumn and the charge control thin film transistor T2′ in the pixel ofodd column to be alternately on.

As an illustration that the charge control thin film transistor T2′ inthe pixel of odd column is a P-type thin film transistor, and the chargecontrol thin film transistor T2 in the pixel of even column is a N-typethin film transistor, as the liquid crystal display panel of columninversion driving mode shows two adjacent frames: in the previous frame,the scan line provides a scan signal of which the duration is a firstduration t1, and the clock signal CK first provides the high voltagelevel of which the duration is a second duration t2 to control thecharge control thin film transistor T2 in the pixel of even column to beon, and meanwhile, the data line provides a positive voltage to make asource voltage of the driving thin film transistor T1 in the pixel ofeven column to be positive for charging the pixel of even column; then,the clock signal CK provides a low voltage level of which the durationis a third duration t3 to control the charge control thin filmtransistor T2′ in the pixel of odd column to be on, and meanwhile, thedata line provides a negative voltage to make the source voltage of thedriving thin film transistor T1 in the pixel of odd column to benegative for charging the pixel of odd column.

The clock signal CK is performed with pulse widthmodulation to adjust the lengths of the second, third duration t2, t3,and thus, the charge durations of the negative voltage and the positivevoltage can be adjusted. The driving thin film transistor T1 and thecharge control thin film transistor T2 are Low Temperature Poly-siliconthin film transistors, oxide semiconductor thin film transistors oramorphous silicon thin film transistors.

Furthermore, as the charge control thin film transistor T2′ in the pixelof odd column is a N-type thin film transistor, and the charge controlthin film transistor T2 in the pixel of even column is a P-type thinfilm transistor, the pixel of odd column needs to be charged first, andthen the pixel of even column is charged. The rest is similar as theaforesaid procedure. The repeated description is omitted here.

With adding the charge control thin filmtransistor T2 in the pixel driving circuit and according to thepositive, negative voltages provided by the data line, the high, lowvoltage levels and pulse widths of the clock signal CK provided to thegate of the charge control thin film transistor T2 are adjusted tocontrol the times of respectively charging the pixels of two adjacentcolumn with the positive, negative voltages, which can balance thecharge effects of the pixels of two adjacent column with the positive,negative voltages to compensate the charge difference to the pixels oftwo adjacent columns caused by the positive, negative voltages formaking the frame display effect uniform.

As an illustration that the chargecontrol thin film transistor T2′ in the pixel of odd column is a P-typethin film transistor, and the charge control thin film transistor T2 inthe pixel of even column is a N-type thin film transistor, N, M are setto be positive integers, and for the pixel of Nth row, the Nth scan lineprovides a scan signal GATE(N) of which the duration is a first durationt1 to the gate of the driving thin film transistor T1 of the pixel ofNth row, and the clock signal CK first provides the high voltage levelof which the duration is a second duration t2 to control the chargecontrol thin film transistor T2 in the pixel of Nth row, even column tobe on, and meanwhile, the corresponding data line S(M) provides apositive voltage to make a source voltage of the charge control thinfilm transistor T1 in the pixel of Nth row, even column to be positivefor charging the pixel of Nth row, even column; then, the clock signalCK provides a low voltage level of which the duration is a thirdduration t3 to control the charge control thin film transistor T2 in thepixel of Nth row, odd column to be on, and meanwhile, the correspondingdata line S(M) provides a negative voltage to make the source voltage ofthe driving thin film transistor T1 in the pixel of Nth row, odd columnto be negative for charging the pixel of Nth row, odd column; the firstduration t1 is a sum of the second duration t2 and the third durationt3.

Scanning row by row sequentially in the same way until driving the frameis accomplished.

Specifically, the third duration t3 is not equal to the second durationt2, and the third duration t3 is larger than the second duration t2.That is to say, the charge duration of the negative voltage is not equalto the charge duration of the positive voltage, and the charge durationof the negative voltage is larger than the charge duration of thepositive voltage to balance the charge effects of the pixels of twoadjacent column with the positive, negative voltages to compensate thecharge difference to the pixels of two adjacent columns caused by thepositive, negative voltages for making the frame display effect uniform.

Step 3, driving the liquid crystal display panel of column inversiondriving mode to show a latter frame.

Please combine FIG. 5 and FIG. 7. As the same illustration that thecharge control thin film transistor T2′ in the pixel of odd column is aP-type thin film transistor, and the charge control thin film transistorT2 in the pixel of even column is a N-type thin film transistor, for thepixel of Nth row, the Nth scan line provides the scan signal GATE(N) ofwhich the duration is the first duration t1 to the gate of the drivingthin film transistor T1 of the pixel of Nth row, and the clock signal CKfirst provides the high voltage level of which the duration is the thirdduration t3 to control the charge control thin film transistor T2 in thepixel of Nth row, even column to be on, and meanwhile, the data lineS(M) provides a negative voltage to make a source voltage of the drivingthin film transistor T1 in the pixel of Nth row, even column to benegative for charging the pixel of Nth row, even column; then, the clocksignal CK provides the low voltage level of which the duration is thesecond duration t2 to control the charge control thin film transistorT2′ in the pixel of Nth row, odd column to be on, and meanwhile, thedata line S(M) provides a positive voltage to make the source voltage ofthe driving thin film transistor T1 in the pixel of Nth row, odd columnto be positive for charging the pixel of Nth row, odd column.

Scanning row by row sequentially in the same way until driving thelatter frame is accomplished.

Furthermore, as shown in FIG. 3, FIG. 4, in the liquid crystal displaypanel of column inversion driving mode, the polarities of the pixels ofevery two adjacent columns are opposite, and the polarities of the samepixel for every two adjacent frames are opposite. Therefore, in the step3, the duration of the high voltage level of the clock signal CK needsto be set to be the third duration t3, and the duration of the lowvoltage level has to be set to be the second duration t2 for ensuringthat the charge duration of the negative voltage is always the thirdduration t3, and the charge duration of the positive voltage is alwaysthe second duration t2. According to the positive, negative voltagesprovided by the data line, the high, low voltage levels and pulse widthsof the clock signal CK provided to the gate of the charge control thinfilm transistor T2 are adjusted to control the times of respectivelycharging the pixels of two adjacent columns with the positive, negativevoltages, which can balance the charge effects of the pixels of twoadjacent columns with the positive, negative voltages to compensate thecharge difference to the pixels of two adjacent columns caused by thepositive, negative voltages for making the frame display effect uniform.

Step 4, cycling steps 2, 3 for driving the liquid crystal display panelof column inversion driving mode to continuously show frames.

Significantly, as the charge control thin film transistor T2′ in thepixel of odd column is a N-type thin film transistor, and the chargecontrol thin film transistor T2 in the pixel of even column is a P-typethin film transistor, correspondingly in the step 2 and the step 3, thepixel of odd column needs to be charged first, and then the pixel ofeven column is charged. The rest of the procedure is similar. Therepeated description is omitted here.

The aforesaid method can accomplish the driving to the liquid crystaldisplay panel of column inversion driving mode, and the charge effect ofthe pixels will not be influenced because the positive, negativepolarities and voltages are different.

In conclusion, the present invention provides a liquid crystal displaypanel of column inversion driving mode and a driving method thereof.With adding the charge control thin film transistor in the pixel drivingcircuit and according to the positive, negative voltages provided by thedata line, the high, low voltage levels and pulse widths of the clocksignal provided to the gate of the charge control thin film transistorare adjusted to control the times of respectively charging the pixels oftwo adjacent column with the positive, negative voltages, which canbalance the charge effects of the pixels of two adjacent column with thepositive, negative voltages to compensate the charge difference to thepixels of two adjacent columns caused by the positive, negative voltagesfor making the frame display effect uniform.
